Evolution of Spatially Inhomogeneous Eco-Systems: An Unified Model Based Approach
نویسنده
چکیده
Recently we have extended our the ”unified” model of evolutionary ecology to incorporate the spatial inhomogeneities of the eco-system and the migration of individual organisms from one patch to another within the same eco-system. In this paper an extension of our recent model is investigated so as to describe the migration and speciation in a more realistic way.

Designing Competency Model for the Head of Tax groups at Iranian National Tax Administration Based on Qualitative Approach
Implementing comprehensive Tax plan and achieving its goals require human resources system to be in harmony with changing environment. Therefore a unified approach is necessary for designing human resources sub- systems. The purpose of this research is to formulate and design a competency framework for tax group heads. This research is embedded in an interpretative paradigm and follows that res...
متن کاملFactors Affecting the Technical Efficiency of Health Systems: A Case Study of Economic Cooperation Organization (ECO) Countries (2004–10)
Background Improving efficiency of health sector is of particular importance in all countries. To reach this end, it is paramount to measure the efficiency. On the other hand, there are many factors that affect the efficiency of health systems. This study aimed to measure the Technical Efficiency (TE) of health systems in Economic Cooperation Organization (ECO) countries during 2004–10 and to d...
متن کاملHamiltonian and Brownian systems with long-range interactions: III. The growth of correlations from the BBGKY hierarchy
We discuss the growth of correlations in systems with weak long-range interactions. Starting from the BBGKY hierarchy, we determine the evolution of the two-body correlation function by using an expansion of the solutions of the hierarchy in powers of 1/N in a proper thermodynamic limit N → +∞. These correlations are responsible for the “collisional” evolution of the system beyond the Vlasov re...
متن کاملA rule-based evaluation of ladder logic diagram and timed petri nets for programmable logic controllers
This paper describes an evaluation through a case study by measuring a rule-based approach, which proposed for ladder logic diagrams and Petri nets. In the beginning, programmable logic controllers were widely designed by ladder logic diagrams. When complexity and functionality of manufacturing systems increases, developing their software is becoming more difficult. Thus, Petri nets as a high l...
